Wyoming continues to maintain one of the most restrictive cannabis policies in the country, with weed remaining illegal for both recreational and general medical use under state law. Unlike many neighboring states that have adopted medical or adult-use programs, Wyoming enforces strict penalties for marijuana possession, with only narrow exceptions for hemp-derived CBD products containing minimal THC. This page explains Wyoming’s current marijuana legality, including recreational prohibitions, limited medical exceptions, possession penalties, legislative history, and how the state compares regionally.

Is marijuana legal in Wyoming
As of 2025, marijuana remains illegal for both recreational and medical use in the state of Wyoming, making it one of the strictest states in the U.S. regarding cannabis laws.
Recreational Use
Possession of marijuana for recreational purposes is completely prohibited in Wyoming. Possessing even small amounts—less than three ounces—is considered a misdemeanor, punishable by up to $1,000 in fines and 12 months in prison. Possession of more than three ounces constitutes a felony, with potential penalties including a fine of $10,000 and a maximum sentence of five years in jail. The state also criminalizes the possession of marijuana paraphernalia.
Medical Use
There is not a robust medicinal marijuana program in Wyoming. Multiple legislative efforts have attempted to introduce or expand medical cannabis access, but none have been approved by the state legislature’s two houses. Limited provisions exist under Wyoming Statute § 35-7-1901, which allows the use of hemp-derived cannabidiol (CBD) oil for patients suffering from intractable epilepsy. Even then, the oil must contain less than 0.3% THC, and access is highly restricted.
Public Sentiment and Legislative Attempts
Surveys indicate growing public support for marijuana reform in Wyoming, particularly for medical use. Nonetheless, the state legislature has remained largely resistant. In 2021 and 2023, bills aimed at legalizing or decriminalizing marijuana were introduced but ultimately failed to advance.
Summary
In conclusion, Wyoming maintains a zero-tolerance policy on marijuana use. Neither recreational nor general medical use is permitted, with only extremely limited exceptions for low-THC CBD oil. Residents and visitors should exercise caution, as the state’s penalties for cannabis-related offenses are severe. Advocacy efforts continue, but as of now, Wyoming is among the last holdouts against broader marijuana legalization in the U.S.
